IMPROVEMENT IN MACHINES FOR BLOCKING HORSE-COLLARS.

Specification forming part of Letters Patent No. 156,189, dated October20, 1374; application filed July i5, 1874.

To all whom it may concern.-

Be it known that I, WILLIAM VAHEY, of Forest, in the county of Lambtonand Province of Ontario, Canada, have invented an Improved Machine forBlocking Horse-Collars, of which the following is a specication:

The nature of this invention relates to an improved machine forstretching and blocking horse-collars into shape; and it consists in thenovel and peculiar construction of a two-part block for stretching andshaping the collar, and the combination therewith of a cord, ring,

and tension-screw, for forming or shaping the crease of the hame-seam,as more fully hereinafter set forth.

Figure l is a perspective view of the ma- Fig. 2 is a longitudinalvertical section of the saine. Fig. 3 is a plan view, showing a collaron the block. Fig. 4 is a crosssection at a:

1n the drawing, A represents a table mounted on legs or a suitableframe. B is the stationary block mounted on said table, and shaped atthe end and sides to form the throat and belly of the collar. B is theremaining part of the block having a pendent shank, I), which slides ina slot, a, in the table. There is anut, c, sunk in the block B', throughwhich nut is tapped a screw, C, which rotates in a longitudinal bearingin the block B, its outer end having a crank with which to rotate it, sothat by such rota-tion the block B may be drawn toward or forced awayfrom the block B.

The collar is laid over the blocks B B', the throat part of the collarover the former, and the neck part over the latter, while the saidcollar is Wet, and it is secured thereon by a plate, D, larger than thetop of the block B laid on top of the latter, and projecting over therim of the collar. This plate is slotted to slip onto a screw, d,projecting up from the block B, and receives a ring-nut, e, to clampdown the collar. The block B is then moved out by its screw until thecollar is put under the proper tension to stretch it to its approximateshape.

At the other end of the table there is erected a three-sided frame, E,in which a follower, E', is reciprocated by a screw, F, sleeved throughthe girt of the frame and tapped through a nut in the follower. A stoutcord, Gr, has its bight laid in the crease of the collar-rim, afterwhich its ends are crossed in a ring, f, and secured to the follower,which is then drawn back by its screw until the cord is forced deep intothe crease of the rim. A few taps from a mallet on the cord brings thecollar into shape, stretching it a little at the same time, when thepressure may be increased by the screw C, and the ollar left on theblocks for an hour or less time to set it permanently in shape, which isbetter than can be got by hand, and with much less labor.

The shape is better than collars shaped on ordinary blocks, for thereason that the throat of the collar may be thrown forward away from thehorses throat, and in like manner the neck may be widened to any desiredextent.

What I claim as my invention, and desire to secure byLetters Patent, is-

In a horse-collar blocking machine, the combination of the table A, thetwo-part solid block B Bf, screw C, nut c, slotted removable plate D,the frame E, follower E', screw F, cord G, and ring f, the several partsbeing constructed and arranged, and the whole operating substantially asdescribed and shown.
